Iowa has a Little Switzerland with 500-foot bluffs, and most Americans have no idea

The 109-mile loop you won’t want to end

Northeast Iowa doesn’t look like the Iowa you picture. No flat fields stretching to the horizon.

Instead, the land rolls into steep green hills and deep river valleys that earned this corner of the state the nickname “Little Switzerland.”

The River Bluffs Scenic Byway traces a 109-mile loop through 13 small towns, past ancient mounds, a towering stone mill, and bluffs that rise 500 feet above the Mississippi.

The loop starts and ends in the same place, which means the drive itself is the whole point.

Why these hills exist and the rest of Iowa doesn’t

Most of Iowa got flattened. The last ice-age glaciers ground across the Midwest and smoothed nearly everything in their path, but they passed right around this corner of the state.

The land here stayed rough, and rivers went to work carving deep channels through the bedrock.

The result is karst country: caves, cold springs, sinkholes, and bluffs layered from limestone that ancient tropical seas laid down. Some of that rock is more than 400 million years old.

You can see it in the cliff faces as you drive the eastern stretch of the byway along the Mississippi valley.

Stand 500 feet above where two rivers become one

Pikes Peak State Park sits on a bluff near McGregor that climbs more than 500 feet above the water below.

Walk to the main overlook and you’re looking straight down at the spot where the Wisconsin River flows into the Mississippi. On a clear day, you can see into three states from there.

The overlook is paved and easy to reach, with a viewing scope and a stone picnic shelter nearby. It’s one of the most photographed places in the entire state, and when you see what’s below, that makes sense.

A boardwalk drops down to one of Iowa’s only waterfalls

Iowa doesn’t have many natural waterfalls. Bridal Veil Falls is one of the few, and a boardwalk trail through a wooded glen leads you right to it.

Water spills over a hard dolomite ledge into a hollow that holds a small cave tucked behind the falls. The half-mile path has a lot of steps, so the walk back up earns its workout.

The falls run fullest after rain and can slow to near nothing in a dry stretch, so timing matters if that’s your main reason for coming.

Walk past a mound shaped like a bear

Along that same boardwalk at Pikes Peak, you pass Bear Mound, an earthwork shaped like a bear that people of the Woodland Culture built more than a thousand years ago.

The park holds more than 60 mounds in all, most of them rounded or long and low along the ground. Tall grass grows on them so their shapes read clearly from a distance.

These are sacred sites, and the trails keep you on the path and off the mounds themselves. Walking past them, knowing how old they are, changes the mood of the whole hike.

Eleven miles of old-growth forest with river views

Pikes Peak has about 11 and a half miles of hiking trails, and the canopy stays thick: oak, hickory, maple, and basswood shade most of the paths even in midsummer.

A longer remote trail heads out to Point Ann, another high bluff above the town of McGregor.

Side boardwalks branch off to quieter overlooks of the Mississippi valley where you can stop and watch the river move below without another person in sight. Come in mid-October and the hillsides go orange and red.

It’s the busiest time of year for good reason.

A six-story stone mill that survived everything

Near Elkader, the Motor Mill rises 90 feet off the bank of the Turkey River. Skilled stonemasons built it from limestone they quarried nearby, with walls five feet thick.

Four other stone buildings stand with it: a stable, an inn, and an icehouse that formed a working complex in the 1860s. Iowa once had hundreds of grist mills.

Almost none that looked like this one still stand.

A restored iron bridge crosses the river right beside it, one lane wide, and the road on either side makes you slow down to take the whole thing in.

Two hundred mounds, 31 shaped like bears and birds

A few miles from Marquette, Effigy Mounds National Monument protects more than 200 ancient mounds built along the bluffs above the Mississippi.

Thirty-one of them are effigies: bears and birds carved into the earth at a scale that only makes sense from above. Great Bear Mound stretches about 137 feet from head to tail.

Fourteen miles of trails climb wooded bluffs to overlooks high above the river. This is the only national monument in Iowa, and it remains a sacred place to many tribes today.

Walk the trails like it.

Guttenberg’s limestone riverfront still looks the part

German immigrants built Guttenberg in the mid-1800s and left their mark in stone.

Many of the original limestone buildings still line the downtown today, and a paved riverwalk runs about two miles along the Mississippi shoreline.

Benches and shaded picnic spots break up the walk so you can sit down, watch a barge move upriver, and stay a while. Forbes once named Guttenberg one of America’s prettiest towns.

Walk the main street and the riverfront on the same afternoon and you’ll get the idea.

Watch a barge rise and fall through a working lock

Guttenberg sits right beside Lock and Dam No. 10, which has been running since 1937.

An observation deck gives you a clear view of barges and boats working through the lock, rising or dropping with the water level.

Nearby stands the last lockmaster’s house on the Upper Mississippi that’s still in its original spot.

Several rooms inside are furnished the way they looked in 1938, which makes the museum feel less like a display and more like someone just stepped out. In winter, bald eagles fish the open water below the dam.

Elkader’s stone arches and the town with the unusual name

Elkader is the county seat, set back into the Turkey River valley hills.

Its Keystone Bridge carries twin stone arches and ranks among the largest of its kind west of the Mississippi. The walkable downtown has several buildings on the National Register of Historic Places.

The town’s name comes from an Algerian leader its early settlers admired in the 19th century, which makes it the only place in the country with that name.

From the bridge, you can look down at a small waterfall where a riverside dam drops the river.

Paddle the Turkey River or browse sand art in McGregor

The paved Elkader River Walk follows the Turkey River at an easy grade, and the 4.4-mile Pony Hollow Trail branches off into shady woods along the water.

The Turkey River draws kayakers, tubers, and anglers throughout the warm months.

In McGregor, a historical museum holds sand-art bottles made by artist Andrew Clemens, delicate work that takes patience to understand.

All along the river valleys, bald eagles, herons, and turkey vultures move through the sky. You’ll spot at least one before the day is done.

Hit the River Bluffs Scenic Byway in northeast Iowa

You can cover the full 109-mile loop in about two hours of straight driving, but the stops will turn it into a full day.

The byway runs through Fayette and Clayton counties, anchored by the river towns of McGregor, Marquette, and Guttenberg. Most of the route is paved, with one optional 5.6-mile gravel stretch.

Pikes Peak State Park takes campground reservations from March through November. Motor Mill runs free guided tours on summer and early-fall weekends.

Fall colors peak in mid-October, and that’s when the crowds come, so plan accordingly.
